Grocery stores, commercial kitchens, hotels, etc., stock a wide range of perishables. Therefore, if you own or run any of these, a commercial refrigerator will be a must-have. These indispensable appliances will ensure your perishable products stay fresh for as long as needed. However, like with all refrigeration systems, issues are sometimes inevitable. Age, unforeseen faults, poor maintenance practices, etc., are among the many issues that may impact your commercial refrigerator's optimal functioning. A faulty commercial refrigerator comes with many losses, including food spoilage and increased energy bills. Therefore, it's critical to know when your commercial refrigerator starts failing to plan for the necessary repairs early enough. Here are the warning signs to watch out for.
Commercial refrigeration systems are designed to keep food and other perishable products chilled or frozen. However, frost build-up is never a good sign, especially if it occurs on the evaporator coils, refrigerator doors, or interior back wall. Typically, temperature issues are the major causes of frost build-up in your commercial refrigerator. If the temperature inside the unit isn't correct, ice may form on the exterior or on the unit's interior back wall. Poor airflow is another reason that your commercial refrigerator could be failing to maintain proper temperatures on the inside. And in most cases, it may be because you have overloaded the unit, blocking the fan and hindering proper airflow. Therefore, try rearranging or reducing the items inside the unit, and if this doesn't work, call a technician.
Temperature differences and fluctuations are other signs to watch out for. Generally, temperature changes manifest in various ways. For instance, if your refrigerator doesn't feel as cold as usual, something could be wrong. Do the refrigerator doors feel warmer to the touch than usual? Chances are you are running low on refrigerant or coolant. Excessive heat at the back of the refrigerator could be a sign of overheating or faulty coils. Water droplets inside the unit or condensation on its exterior are other indicators of temperature issues. Usually, this will happen if you have faulty door seals that fail to keep the cooled air inside the unit from escaping.
A noisier commercial refrigerator is usually a sign that something is wrong. Generally, your commercial refrigerator won't run silently, and you'll hear a low humming sound. However, it's imperative not to ignore unusual sounds like clicking, rattling and squeaking. In most cases, such sounds indicate problems with the compressor, evaporator, motor, fan, and other mechanical components.
